A question worth sitting with: are your six ETFs really six different bets?

Wednesday brought a mixed session on the ASX, with a familiar split between old-economy sectors holding up and growth-tilted names taking the weight. It is also a good day to ask whether the portfolio you think you have is the portfolio you actually own.

A question worth sitting with

Imagine you spread your savings across six different ETFs. You feel covered. Different names, different fund managers, different labels on the tin. But what if four of those six funds are largely holding the same large companies underneath? The diversification you see in your account might be more cosmetic than real. A handful of mega-cap names could be quietly driving most of your returns, and most of your risk, without it ever being obvious from the fund names alone.

Here is the question worth sitting with this week: if you stripped away the fund wrappers and looked only at the underlying companies, how many truly different businesses do you actually own?

What moved today

Information Technology was the heaviest drag today, falling 2.60%, with Energy the clear bright spot at up 1.78%. Utilities and Health Care each slipped less than one percent. Communication Services was also slightly softer.

Among the most-affected names, WES fell 2.69% and CBA dropped 1.76%, a reminder that large, widely-held stocks can move a portfolio meaningfully even when the headline index loss looks contained. ANZ was also down 2.61%, and consumer staples names WOW gave back 1.73%. The session illustrated how concentrated the ASX is in a small club of companies. When those names have a difficult day, a broad index fund feels it quickly.

A lesson worth keeping

Owning six ETFs is not the same as owning six different portfolios. Many broad Australian and global equity funds draw from the same pool of large-cap names, because index construction rules push them all toward the biggest companies by market value. The result is what analysts sometimes call overlapping exposure. You pay multiple management fees, you see multiple fund names, but the underlying risk is far more concentrated than it appears.

A simple exercise: list the top ten holdings of each fund you own and see how many names appear more than once. If the same companies keep showing up, that tells you something important about where your real exposure sits. Counting funds is not the same as counting risks.

As always, none of this is personal financial advice. PortLens is a telescope, not a casino. Take the time to look clearly at what you own, and what questions that raises for you.
